How much could it cost to pay someone else to do this? Surely less than a doctor makes doing it... It can become its own profession. It's a separate skill - separate from what a doctor should be focusing on.

On a side note, it seems that a lot of professions would benefit from having an assistant - a thing that seems to have disappeared - if what I've seen in old movies in shows is to be believed. Another side-case of this is the fact that technical people tend to be promoted into management roles and have to deal with attendance and time-sheets - why not have someone else do it? The work only suffers.
